MODEL 830-004 Power Supply Module DESCRIPTION The 830-004 is a single output isolated DC/DC converter with an input range of 110 to 375 Vdc. This allows the module to operate from any rectified 80 to 265 Vac line, corresponding to line voltages found worldwide. Fixed output voltages between 5 to 24 Vdc are available to suit a variety of applications. Low cost, high reliability and small dimensions are the main characteristics of this design. The use of an advanced PWM provides for stable and efficient operation over a wide load range.

Most applications require the addition of output capacitance. The capacitor’s voltage rating should be selected in correlation to the output voltage of the 830-004. Choose sufficient capacitance to reduce the output ripple to an acceptable level for the application. A 47µF electrolytic should generally be suitable and should be located close to the output pins. To operate from an AC line, a bridge rectifier must be added. A DB104 bridge rectifier or four IN4005 configured as pictured. Diodes should be 600 volts, 1 amp and should be used in conjunction with a 47µF input capacitor. Choose the capacitor voltage rating appropriately. 7-16 Model 830-004 ELECTRICAL PARAMETER CONDITIONS MIN. 50% Rated Output Power -5% 20%-80% Rated Output Power Vin min. to max. Input Voltage TYP.
